Abstract

Systems, methods, and other embodiments described herein relate to charging a battery of an electric vehicle while the electric vehicle is hovering. In one embodiment, a method includes, responsive to determining that an electric vehicle does not include a receiver pad, inserting the receiver pad into the electric vehicle that is hovering in the air at a charging station. The method includes determining a space above a transmitter pad for the electric vehicle to hover based, at least in part, on a location and a size of the transmitter pad. The method includes charging a battery to a threshold value through the receiver pad.

Claims (47)

1. A method comprising:

responsive to determining that an electric vehicle does not include a receiver pad, inserting the receiver pad into the electric vehicle while it is hovering in air at a charging station;

determining a space above a transmitter pad for the electric vehicle to hover based, at least in part, on a location and a size of the transmitter pad; and

charging a battery to a threshold value through the receiver pad.

2. The method of claim 1 , wherein inserting the receiver pad into the electric vehicle includes:

communicating to request insertion of the receiver pad.

3. The method of claim 1 , wherein inserting the receiver pad into the electric vehicle includes:

causing a mechanical arm to insert the receiver pad according to a communication requesting the receiver pad.

4. The method of claim 1 , wherein determining the space above the transmitter pad for the electric vehicle to hover includes:

detecting the location and the size of the transmitter pad;

determining a size of a magnetic field between the receiver pad and the transmitter pad based on the location and the size of the transmitter pad; and

determining the space above the transmitter pad for the electric vehicle to hover based on the size of the magnetic field between the receiver pad and the transmitter pad.

5. The method of claim 4 , wherein detecting the location and the size of the transmitter pad includes:

detecting the location and the size of the transmitter pad using at least one of a sensor and communicating with the charging station.

6. The method of claim 1 , further comprising:

responsive to the battery reaching the threshold value, removing the receiver pad from the electric vehicle using a mechanical arm.

7. The method of claim 1 , further comprising:

responsive to the battery reaching the threshold value, removing the receiver pad from the electric vehicle by communicating with the charging station to request removal of the receiver pad.

8. A system, comprising:

one or more processors

a memory communicably coupled to the one or more processors and storing:

a control module including instructions that, when executed by the one or more processors, cause the one or more processors to:

responsive to determining that an electric vehicle does not include a receiver pad, insert the receiver pad into the electric vehicle while it is hovering in air at a charging station;

determine a space above a transmitter pad for the electric vehicle to hover based, at least in part, on a location and a size of the transmitter pad; and

charge a battery to a threshold value through the receiver pad.

9. The system of claim 8 , wherein the control module includes instructions to insert the receiver pad into the electric vehicle including instructions to communicate to request insertion of the receiver pad.

10. The system of claim 8 , wherein the control module includes instructions to insert the receiver pad into the electric vehicle including instructions to cause a mechanical arm to insert the receiver pad according to a communication requesting the receiver pad.

11. The system of claim 8 , wherein the control module includes instructions to determine the space above the transmitter pad for the electric vehicle to hover including instructions to:

detect the location and the size of the transmitter pad;

determine a size of a magnetic field between the receiver pad and the transmitter pad based on the location and the size of the transmitter pad; and

determine the space above the transmitter pad for the electric vehicle to hover based on the size of the magnetic field between the receiver pad and the transmitter pad.

12. The system of claim 11 , wherein the control module includes instructions to detect the location and the size of the transmitter pad including instructions to:

detect the location and the size of the transmitter pad using at least one of a sensor and communicating with the charging station.

13. The system of claim 8 , wherein the control module includes instructions to, responsive to the battery reaching the threshold value, remove the receiver pad from the electric vehicle using a mechanical arm.

14. The system of claim 8 , wherein the control module includes instructions to, responsive to the battery reaching the threshold value, remove the receiver pad from the electric vehicle by communicating with the charging station to request removal of the receiver pad.

15. A non-transitory computer-readable medium including instructions that, when executed by one or more processors, cause the one or more processors to:

responsive to determining that an electric vehicle does not include a receiver pad, insert the receiver pad into the electric vehicle while it is hovering in air at a charging station;

determine a space above a transmitter pad for the electric vehicle to hover based, at least in part, on a location and a size of the transmitter pad; and

charge a battery to a threshold value through the receiver pad.

16. The non-transitory computer-readable medium of claim 15 , wherein the instructions to insert the receiver pad into the electric vehicle include instructions to request insertion of the receiver pad.

17. The non-transitory computer-readable medium of claim 15 , wherein the instructions to insert the receiver pad into the electric vehicle include instructions to cause a mechanical arm to insert the receiver pad according to a communication requesting the receiver pad.

18. The non-transitory computer-readable medium of claim 15 , wherein the instructions to determine the space above the transmitter pad for the electric vehicle to hover include instructions to:

detect the location and the size of the transmitter pad;

determine a size of a magnetic field between the receiver pad and the transmitter pad based on the location and the size of the transmitter pad; and

determine the space above the transmitter pad for the electric vehicle to hover based on the size of the magnetic field between the receiver pad and the transmitter pad.

19. The non-transitory computer-readable medium of claim 18 , wherein the instructions to detect the location and the size of the transmitter pad include instructions to detect the location and the size of the transmitter pad using at least one of a sensor and communicating with the charging station.

20. The non-transitory computer-readable medium of claim 15 , wherein the instructions include instructions to, responsive to the battery reaching the threshold value, remove the receiver pad from the electric vehicle using a mechanical arm.
